The non-Euclidean Lobachevsky imaginary 4-space (2) is also called the Lobachevsky imaginary 4-space. It is natural that QFT based on momentum representation of the form (l)- (2) must predict new physical phenomena at energies . In principle, the parameter may turn out to be close to the Planck mass
GeV. Then, the new scheme should include quantum gravity. The standard QFT corresponds to the “small” 4- momentum approximation
, which formally can be performed by letting (flat limit). Such features of the considered generalization of the theory as geometricity and minimality are intriguing. This is due to the fact that the Minkowski momentum 4-space having a constant zero curvature is a degenerate limiting form of each of the spaces with constant nonzero curvature (l)-(2). If we substitute in (2) standard
and
receive the quantum version of the de Setter equations (2) in five-dimensional field equation
, (3) . We deliberately use in (3) the normal units to emphasize those three universal constants , and are grouped into one parameter-fundamental length
. Eq. (3) may be considered as the “fundamental” equation of motion. It is natural to extend the term “fundamental” to eq. (3) itself (for short f.e.). All the fields independent of their tensor (or spinor) character must obey eq. (3) since similar universality is inherent in the “classical” prototype, i.e. - de Sitter p-space (2). As applied to scalar, spinor, vector and other fields we shall write down the five-dimensional wave function
in the form
,
,
,.. . The field theory based on f.e. (3) turns out to be more consistent and more general than the scheme developed in the de Sitter p-space (2). Thus, by virtue of (2) the 4-momentum components should obey the constraint
, which does not follow from eq. (3). Indeed, passing in (3) to a mixed (
representation we get the equation
, (4) having a solution at all
including the region
. Consequently,
now takes both real and pure imaginary values. For further application let us define this quantity as a generalized function
(5) with (5) one can easily write down the general solution of (4)
, (6) where the “initial data” of and
are determined at all values of 4-momenta. The Fourier transformation of (6), results in the formal solution of fundamental equation (3)
